The main objective of this paper is to contribute to India’s macroeconomic database of Input-Output Tables (IOTs) and Social Accounting Matrices (SAMs). The Central Statistics Office (CSO) of the Government of India has been regularly publishing IOTs since the 1960s. The latest table was published in 2012 for the reference year 2007-08. Although a Supply and Use Table (SUT) is available for 2012-13, a corresponding IOT has not been presented thus far. Given the significance of these databases in understanding complex inter-relationships within economies, it is imperative that they are regularly made available to practitioners in the field. Therefore, to maintain continuity, this paper proposes to transform the SUTs into a symmetric I-O flow matrix. A 140 x 140 commodity matrix will comprise a uniquely detailed database, useful to practitioners and policy makers alike. We also propose to compile satellite accounts based on the new I-O table. Since the government has not published such matrices for several years, we develop a methodology to undertake their construction. In addition, this study seeks to enrich India’s anthology of SAMs by constructing a disaggregated matrix of 140 sectors for the Indian economy. Such an extensive database can be used for I-O, SAM and computable general equilibrium (CGE) modelling of energy, employment and climate policies for India.
